Hey guys, I'm relatively new to circuitry (complete beginner ) and I am requiring some help with a LED lighting project.
The main aim of the project is to create a circuit that lights up an LED using a rotary switch to chose between 1 of 3 circuits.
1) a LDR that powers the LED when activated with light
2) a LDR that powers the LED when there is no light
3) and the 3rd mode provides constant power to the LED.

I was hoping that someone could help me work out a circuit that could do this, The main bit that I need help with is connecting the 3 circuits together and to the switch so that they can power the LED. I can already build the LDR circuits but if anybody has any suggestions for LDR circuits they would also be appreciated.
Cheers Tom

@Bernard - thank you very much,with my limited circuitry knowledge I was able to identify the rotary switch, 555 IC timer, LDR and a resistor and transistor.
Would it be possible for you to label the different components or or just list the components you used?@mcgyvr You are correct and I will draw it out and upload the circuit diagram later.@Dodgydave I will be using 5v.
Thanks
